概率(lv)篩(shai)(shai)(shai)(shai)是結(jie)合鐵路道碴(cha)(cha)篩(shai)(shai)(shai)(shai)分需求研發的(de)一種新(xin)型篩(shai)(shai)(shai)(shai)分設(she)備,是以道碴(cha)(cha)沿篩(shai)(shai)(shai)(shai)面相(xiang)對滑動的(de)原理和鏈結(jie)傳動的(de)多邊形效應為依據而設(she)計的(de)鐵路道碴(cha)(cha)清(qing)篩(shai)(shai)(shai)(shai)機(ji)上使(shi)用的(de)新(xin)型篩(shai)(shai)(shai)(shai)分機(ji)構(gou)。概率(lv)篩(shai)(shai)(shai)(shai)能使(shi)粒徑(jing)(jing)小的(de)碎(sui)碴(cha)(cha)得到(dao)較多的(de)篩(shai)(shai)(shai)(shai)分,而粒徑(jing)(jing)大(da)的(de)碎(sui)碴(cha)(cha)其篩(shai)(shai)(shai)(shai)分則很(hen)少,從而大(da)大(da)地提高了篩(shai)(shai)(shai)(shai)分率(lv),可延長清(qing)篩(shai)(shai)(shai)(shai)周期一倍左(zuo)右。
通常所說的概(gai)率(lv)篩(shai)(shai)是振(zhen)動(dong)(dong)概(gai)率(lv)篩(shai)(shai),其(qi)篩(shai)(shai)面(mian)是靠激振(zhen)裝置(zhi)進(jin)行直(zhi)線振(zhen)動(dong)(dong)的。這種(zhong)概(gai)率(lv)篩(shai)(shai)目前已廣泛地應用于冶金、建(jian)材及煤(mei)炭等工業(ye)部門(men),用于對中、細(xi)粒(li)物料(liao)的粒(li)度分(fen)級。振(zhen)動(dong)(dong)概(gai)率(lv)篩(shai)(shai)與變通振(zhen)動(dong)(dong)篩(shai)(shai)在結構上的主要區別是,振(zhen)動(dong)(dong)概(gai)率(lv)篩(shai)(shai)采用多層(ceng)(一般為3~6層(ceng))、大傾角(一般為30°~60°)、大篩(shai)(shai)孔(kong)(kong)(篩(shai)(shai)孔(kong)(kong)尺(chi)寸(cun)是分(fen)離粒(li)度的2~10倍)的篩(shai)(shai)面(mian)。
概率(lv)篩(shai)(shai)(shai)(shai)(shai)(shai)和(he)(he)(he)(he)普通振(zhen)(zhen)動篩(shai)(shai)(shai)(shai)(shai)(shai)基(ji)本結構是(shi)一(yi)(yi)樣的(de),也(ye)(ye)由(you)篩(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)、激(ji)振(zhen)(zhen)器(qi)和(he)(he)(he)(he)支承(吊掛)裝置三(san)部分(fen)組(zu)(zu)成。但結構又具有層(ceng)(ceng)(ceng)數(shu)(shu)多(duo)、傾(qing)(qing)角(jiao)大(da)(da)(da)(da)、篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)大(da)(da)(da)(da)和(he)(he)(he)(he)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)短(duan)四(si)大(da)(da)(da)(da)特點(dian)。概率(lv)篩(shai)(shai)(shai)(shai)(shai)(shai)的(de)篩(shai)(shai)(shai)(shai)(shai)(shai)箱(xiang)由(you)篩(shai)(shai)(shai)(shai)(shai)(shai)框和(he)(he)(he)(he)3~5個篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)組(zu)(zu)成,篩(shai)(shai)(shai)(shai)(shai)(shai)框是(shi)用(yong)鋼(gang)板和(he)(he)(he)(he)型鋼(gang)焊接或(huo)鉚接的(de)多(duo)邊形箱(xiang)體,篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)裝設(she)在(zai)(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)框上(shang)(shang)(shang)(shang)。每(mei)個篩(shai)(shai)(shai)(shai)(shai)(shai)框上(shang)(shang)(shang)(shang)可(ke)安置數(shu)(shu)個傾(qing)(qing)斜(xie)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian),目前(qian),多(duo)數(shu)(shu)概率(lv)篩(shai)(shai)(shai)(shai)(shai)(shai)裝有三(san)層(ceng)(ceng)(ceng)或(huo)五層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)。各(ge)(ge)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)坡(po)度(du),自上(shang)(shang)(shang)(shang)而(er)下(xia)(xia)(xia)遞增。由(you)于(yu)考慮到物(wu)料在(zai)(zai)(zai)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)一(yi)(yi)有較大(da)(da)(da)(da)的(de)運行速度(du),所以采(cai)用(yong)大(da)(da)(da)(da)的(de)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)傾(qing)(qing)角(jiao)。上(shang)(shang)(shang)(shang)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)傾(qing)(qing)角(jiao)為(wei)(wei)15°~35°,并以上(shang)(shang)(shang)(shang)層(ceng)(ceng)(ceng)傾(qing)(qing)角(jiao)為(wei)(wei)準,以下(xia)(xia)(xia)各(ge)(ge)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)按4°~6°遞增.的(de)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)為(wei)(wei)大(da)(da)(da)(da),其它(ta)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)尺寸自上(shang)(shang)(shang)(shang)而(er)下(xia)(xia)(xia)逐層(ceng)(ceng)(ceng)遞減.一(yi)(yi)般上(shang)(shang)(shang)(shang)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)在(zai)(zai)(zai)販篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)要比分(fen)離(li)粒(li)度(du)大(da)(da)(da)(da)10~15倍;下(xia)(xia)(xia)一(yi)(yi)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)至少也(ye)(ye)應(ying)是(shi)分(fen)離(li)粒(li)度(du)的(de)1.5~2倍;中間各(ge)(ge)層(ceng)(ceng)(ceng)篩(shai)(shai)(shai)(shai)(shai)(shai)的(de)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong),可(ke)在(zai)(zai)(zai)上(shang)(shang)(shang)(shang)和(he)(he)(he)(he)下(xia)(xia)(xia)兩(liang)種(zhong)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)之(zhi)間酌情選取。因為(wei)(wei)只有在(zai)(zai)(zai)采(cai)取大(da)(da)(da)(da)傾(qing)(qing)角(jiao)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)的(de)條(tiao)件(jian)下(xia)(xia)(xia),才有可(ke)能采(cai)用(yong)遠大(da)(da)(da)(da)于(yu)分(fen)離(li)粒(li)度(du)的(de)大(da)(da)(da)(da)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian),故篩(shai)(shai)(shai)(shai)(shai)(shai)面(mian)(mian)(mian)傾(qing)(qing)角(jiao)和(he)(he)(he)(he)篩(shai)(shai)(shai)(shai)(shai)(shai)孔(kong)大(da)(da)(da)(da)小應(ying)統一(yi)(yi)考慮。
在工作(zuo)原理上,它與普通(tong)振(zhen)動(dong)篩(shai)(shai)也有明顯的(de)差別,概率篩(shai)(shai)能動(dong)地利(li)用了概率原理,從(cong)而以很快的(de)速度完成(cheng)整(zheng)個篩(shai)(shai)分過(guo)程,使物(wu)料篩(shai)(shai)分所(suo)需的(de)時(shi)間僅為變(bian)通(tong)振(zhen)動(dong)篩(shai)(shai)的(de)1/3~1/20,而其單位篩(shai)(shai)面(mian)(mian)面(mian)(mian)積的(de)處(chu)理能力比普通(tong)振(zhen)動(dong)篩(shai)(shai)大5~10倍。因此(ci),可以認為在概率篩(shai)(shai)中(zhong)所(suo)進行(xing)的(de)篩(shai)(shai)分屬于(yu)"快速篩(shai)(shai)分"。
此外,振動概率篩(shai)體積小、重量輕、篩(shai)孔不易堵(du)塞;一臺(tai)篩(shai)分(fen)(fen)機(ji)同(tong)時可以得到幾個粒(li)(li)級(ji)的(de)(de)(de)產(chan)物(wu),篩(shai)分(fen)(fen)粒(li)(li)度(du)范圍(wei)寬。但是(shi)由于概率篩(shai)結構(gou)特(te)點(dian)的(de)(de)(de)限制,如一臺(tai)設備了出多種產(chan)品時,其配置上較為(wei)復雜。更主要(yao)的(de)(de)(de)弱點(dian)是(shi)篩(shai)分(fen)(fen)精確度(du)低,不同(tong)粒(li)(li)度(du)的(de)(de)(de)物(wu)料,相互間有(you)一定程度(du)的(de)(de)(de)滲混。基于這(zhe)點(dian)則將在(zai)概率篩(shai)上進行的(de)(de)(de)篩(shai)分(fen)(fen)過程稱作(zuo)近似篩(shai)分(fen)(fen)。
概率篩和直線(xian)篩的區別(bie)
一、概(gai)率篩與直線篩分物料區別
概率篩(shai)大多使用(yong)在冶(ye)金,煤炭等礦(kuang)工領域,主要篩(shai)分(fen)碎碴,砂石(shi)等物(wu)料(liao),直線篩(shai)使用(yong)行業(ye)更(geng)廣泛,適合篩(shai)分(fen)精細化物(wu)料(liao)。食品,醫藥,化工,冶(ye)金等行業(ye),可以(yi)篩(shai)分(fen)芝麻,花生,中藥粉,化肥(fei),磨(mo)料(liao)等物(wu)料(liao)
二(er)、概率篩比直線(xian)篩傾斜角(jiao)大(da)
由于概(gai)率篩(shai)(shai)(shai)(shai)(shai)的(de)層(ceng)數(shu)比較多,為了使物料(liao)快速有效(xiao)篩(shai)(shai)(shai)(shai)(shai)分,所(suo)以(yi)(yi)采用大傾(qing)斜角(jiao)篩(shai)(shai)(shai)(shai)(shai)面(mian),最上層(ceng)的(de)篩(shai)(shai)(shai)(shai)(shai)面(mian)傾(qing)斜角(jiao)設(she)置在15°-35°之(zhi)間,以(yi)(yi)下的(de)各層(ceng)篩(shai)(shai)(shai)(shai)(shai)面(mian)以(yi)(yi)最上層(ceng)篩(shai)(shai)(shai)(shai)(shai)面(mian)為基(ji)準按4°-6°遞(di)減,對于概(gai)率篩(shai)(shai)(shai)(shai)(shai)來說,大傾(qing)斜角(jiao)的(de)設(she)置可以(yi)(yi)使物料(liao)得(de)到(dao)更大面(mian)積的(de)篩(shai)(shai)(shai)(shai)(shai)分,物料(liao)充分接觸篩(shai)(shai)(shai)(shai)(shai)網,層(ceng)層(ceng)過濾(lv)以(yi)(yi)達到(dao)良好的(de)篩(shai)(shai)(shai)(shai)(shai)分效(xiao)果;直線篩(shai)(shai)(shai)(shai)(shai)的(de)篩(shai)(shai)(shai)(shai)(shai)面(mian)傾(qing)斜角(jiao)在0°-25°之(zhi)間。
三、概率篩比直(zhi)線篩篩孔(kong)大(da)
概率篩的(de)(de)(de)篩孔比直(zhi)線篩的(de)(de)(de)篩孔大(da),篩孔的(de)(de)(de)大(da)小主要對應物料(liao)(liao)的(de)(de)(de)篩分(fen)細度(du)(du)或精(jing)度(du)(du),一般來說(shuo),直(zhi)線篩的(de)(de)(de)篩孔尺寸(cun)比篩分(fen)物料(liao)(liao)粒(li)徑大(da)一點即可,但概率篩的(de)(de)(de)篩孔遠遠大(da)于是(shi)分(fen)離粒(li)度(du)(du)的(de)(de)(de)2-10倍(bei),最上層的(de)(de)(de)篩孔最大(da),以下篩層依次遞減,最下面的(de)(de)(de)篩孔尺寸(cun)至少也是(shi)分(fen)離粒(li)度(du)(du)的(de)(de)(de)1.5-2倍(bei)。
四、概率篩(shai)比直線篩(shai)篩(shai)分產量大
概率(lv)篩(shai)(shai)(shai)(shai)(shai)和直線篩(shai)(shai)(shai)(shai)(shai)都是(shi)方形,概率(lv)篩(shai)(shai)(shai)(shai)(shai)比(bi)(bi)直線篩(shai)(shai)(shai)(shai)(shai)的(de)篩(shai)(shai)(shai)(shai)(shai)面短,篩(shai)(shai)(shai)(shai)(shai)面越(yue)(yue)長物料篩(shai)(shai)(shai)(shai)(shai)分(fen)的(de)時(shi)間(jian)就越(yue)(yue)長,所篩(shai)(shai)(shai)(shai)(shai)分(fen)細(xi)度就越(yue)(yue)精(jing)確,但每小時(shi)生產(chan)(chan)產(chan)(chan)量(liang)(liang)就越(yue)(yue)低;篩(shai)(shai)(shai)(shai)(shai)面越(yue)(yue)短,篩(shai)(shai)(shai)(shai)(shai)分(fen)速度就快,投料頻次多(duo),所篩(shai)(shai)(shai)(shai)(shai)分(fen)的(de)產(chan)(chan)量(liang)(liang)就會越(yue)(yue)多(duo)。相同參數(shu)下,概率(lv)篩(shai)(shai)(shai)(shai)(shai)每小時(shi)的(de)產(chan)(chan)量(liang)(liang)比(bi)(bi)直線篩(shai)(shai)(shai)(shai)(shai)大。
概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai)的(de)(de)篩(shai)(shai)(shai)面均作直(zhi)(zhi)線(xian)振(zhen)動,故與(yu)普通(tong)振(zhen)動篩(shai)(shai)(shai)一(yi)(yi)樣,可采用(yong)雙軸慣(guan)性激(ji)(ji)振(zhen)器(qi)(qi),用(yong)兩臺(tai)電動機(ji)(ji)(ji)分別(bie)帶(dai)動。對(dui)于體積小、重量(liang)輕的(de)(de)概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai),可作用(yong)一(yi)(yi)對(dui)振(zhen)動電機(ji)(ji)(ji)直(zhi)(zhi)接裝(zhuang)(zhuang)在(zai)篩(shai)(shai)(shai)箱(xiang)上(shang)(shang)激(ji)(ji)振(zhen),兩激(ji)(ji)振(zhen)電動機(ji)(ji)(ji)自同步運轉,產生直(zhi)(zhi)線(xian)振(zhen)動。由于篩(shai)(shai)(shai)箱(xiang)和(he)激(ji)(ji)振(zhen)器(qi)(qi)之(zhi)(zhi)間的(de)(de)聯接方式(shi)不同,故有(you)兩種不同激(ji)(ji)振(zhen)系(xi)統的(de)(de)激(ji)(ji)振(zhen)器(qi)(qi):一(yi)(yi)種是激(ji)(ji)振(zhen)器(qi)(qi)直(zhi)(zhi)接固接在(zai)篩(shai)(shai)(shai)條止,像普通(tong)直(zhi)(zhi)線(xian)振(zhen)動篩(shai)(shai)(shai),這種概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai)是線(xian)性振(zhen)動系(xi)統。另一(yi)(yi)種是激(ji)(ji)振(zhen)器(qi)(qi)安(an)裝(zhuang)(zhuang)在(zai)平(ping)衡架上(shang)(shang),平(ping)衡架與(yu)篩(shai)(shai)(shai)箱(xiang)之(zhi)(zhi)間是彈性聯接,篩(shai)(shai)(shai)箱(xiang)用(yong)彈簧(huang)吊(diao)(diao)掛,這種概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai)是雙質量(liang)振(zhen)動系(xi)統。概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai)基(ji)本上(shang)(shang)都采用(yong)帶(dai)有(you)彈簧(huang)的(de)(de)懸吊(diao)(diao)裝(zhuang)(zhuang)置,重量(liang)輕的(de)(de)小篩(shai)(shai)(shai)分機(ji)(ji)(ji)用(yong)圓柱螺(luo)旋(xuan)彈簧(huang)直(zhi)(zhi)接中吊(diao)(diao)掛裝(zhuang)(zhuang)置進行調節(jie)。根據廠(chang)房條件和(he)配置的(de)(de)需要,概(gai)(gai)率(lv)(lv)篩(shai)(shai)(shai)也(ye)可安(an)裝(zhuang)(zhuang)成座式(shi),和(he)直(zhi)(zhi)線(xian)振(zhen)動篩(shai)(shai)(shai)一(yi)(yi)樣,篩(shai)(shai)(shai)箱(xiang)通(tong)過一(yi)(yi)組彈簧(huang)支承在(zai)機(ji)(ji)(ji)座上(shang)(shang)。
